I use to have a set of wooden bowls shaped like leaves, and I miss those things! Decided to make one I can 3d print. Turned out pretty nice.
The model has some curves on the undersize, so I recommend printing the model with supports. (I've got a AMS with PLA supports going for the best results) Yeah! Sorry, I could have given it a more print friendly bottom, but that'd take away from the design. That PLA support material works wonders though.
I'd suggest scaling it up or down to fit your desired size!
